This female great white was 6.1 m (20 ft) long. However, there was a report considered reliable by some experts in the past, of a larger great white shark specimen from Cuba in 1945. This specimen was 6.4 m (21 ft) long and had a body mass estimated at 3,324 kg (7,328 lb).
ALS (amyotrophic lateral sclerosis), also known as Lou Gehrigs disease, is a progressive disease of the motor neurons (nerve cells that control the skeletal muscles). As motor neurons are affected, gradual weakness, atrophy, and paralysis of the skeletal muscles occur.
Signs and Symptoms. ALS affects the upper motor neurons, which are in the brain, and the lower motor neurons, which are in the spinal cord and brainstem. Upper motor neuron degeneration generally causesspasticity (tightness in a muscle), while lower motor neuron degeneration causes muscle weakness, muscle atrophy(shrinkage of muscles) and twitching. These can occur in combination in ALS, as upper and lower motor neurons are being lost at the same time.
